Patented Jan. 22, 1935 PENCIL R CRAYON CASE Friedrich Krauss, Vienna, Austria Applicatie 3 Claims.

This invention relates to improved pencil cases and more particularly to devices for sharpening the lead of pencil cases or crayons.

Two modes of carrying out the present inven- 5 tion are illustrated by way of examples on the accompanying sheet of drawings in which Figs. 1 and 2 are part-sectional views of pencil cases.

The pencil case shown in Fig. 1 consists of a sheath 1, provided with a tapered mouthpiece 3 and with sharpening tools 4, mounted on plate springs 5. The latter are fixed to handles 14 or the like, extending outward through long slots 15 in the sheath 1. In the inoperative position, the sharpening tools 4 do not co-operate with the lead 6 of the pencil case. If it is desired to sharpen the lead, the same is withdrawn into the sheath 1 until its forward end is disposed between the sharpening tools. Then the latter are pushed upward by means of the handles 14, until the sharpening tools co-operate with the inner wall of the tapered mouthpiece 3 and are pressed inward onto the lead 6. The lead is sharpened by turning the same with respect to the sheath 1. 16 designates guides through which the springs 5 pass and which have the tendency to maintain the springs in the inoperative position.

The crayon shown in Fig. 2 consists gf a sheath 1 with a tapered mouthpiece 3 and a sleeve `17, carrying the Sharpeners 4, 5 and mounted longitudinally slidable in said sheath. The sleeve 17 rests on a stop 18 xed to the sheath and an internally threaded screw-shaft 19, provided with an operating handle 20, is secured to said sleeve and serves for screwing in and out the lead-holder 21. Only rotary but not longitudinal movement being allowed between the sleeve and the screwn October 17, 1932, Serial No. 638,224 I Austria October 17, 1931 shaft. A cylindric spiral spring 22 is arranged around said shaft and disposed within the sheath between the stop 18 and a washer 23 xed to the screw-shaft. If it is desired to sharpen the lead 6,

the lead-holder 21 is screwe the screw shaft 19 and whenever the point of the lead is disposed between the Sharpeners 4, the

screw-shaft 19, 20 is pushed inward by hand whereby the sleeve 17 with its lead-holder 21 and Sharpeners 4 are raised against the action of the spring 22 until the Sharpeners co-operate with the inner wall of the tapered mouthpiece 3 and are pressed inward onto the lead 6. The lead 6 is sharpened by turning the same through the agency of the screw 19,

20. The spring 22 returns the sleeve 17 and Sharpeners 4 into the initial or inoperative position. 16 designates guides for the springs 5 of the Sharpeners 4, while 24 is a bearing for the sleeve 17.
